With proper constant folding code, both functions can be reduced to a single LOAD_CONST and a RETURN_VALUE (or, definitely, by a single instruction at all with an advanced peephole optimizer).
Lists are mutable, you can't optimize the creation of list literals by storing them as singleton constants. Regards Antoine.
